Hi,Dear,Thanks for your query to HCM. Dear I read your query and reviewed it with context to your query facts. I understood your health concerns and feel Concerned about them. Based on the facts of your query, you seem to suffer from- Pus with Mucus with severe colitis from Cl.difficile. As you still have multiple motions with a known cl.Difficile attack with watery diarrhea. This could be post proctitis -anal abscess/or rectal abscess burst open in the passage to be drained down. These are the possibilities. CT /MRI Scan of the area would fix the extent of the abscesses if any,if the condition gets worstened. This yellow per rectal discharge, has nothing to do with the gall bladder disease of yours. The sever itch after the yellow pus is due to the perianal dermatitis from severe watery diarrhea you are having simultaneously. Hope this would help you to reduce worry with your problem. Take care and wish you to recover fast and Live healthy. Hope this reply would help you to plan further treatment with your family and specialist doctors there. Welcome for any further query in this regard. Good Day!! Dr.Savaskar M.N. Senior Surgical Specialist M.S.Genl-CVTS
